The Single, the Whole, and the Pooled: Implications of Tissue Choice for Stable Isotope Analysis

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT In the exciting era of non‐invasive tissue sampling and data reuse via open access databases, it is increasingly challenging to ensure comparability of sample types for stable isotope analysis in ecology. According to the theoretical predictions about the changes in the stable isotope values between prey and consumers and tissue turnover rates,

A novel approach to estimate non‐algal particle absorption for improved retrieval of pigment concentrations in coastal waters

Limnology and Oceanography: Methods, EarlyView.
Abstract Phytoplankton play a central role in ocean biogeochemistry and understanding their composition and variability is critical for monitoring marine ecosystem dynamics. Continuous spectrophotometric measurements (using a Seabird Sci. AC‐S) along ship tracks enable high‐resolution measurements of particle spectral absorption (apλ$$ {a}_p\left ...

Experimental and field evidence indicate that islet‐nesting tundra birds experience reduced nest predation and benefit indirectly from high snow goose densities

Oikos, EarlyView.
Landscape features can shape the occurrence and strength of predator–prey interactions by influencing predation risk and prey distribution. In the High Arctic, some bird species select nesting sites with physical features that impede access for their main terrestrial predator, the Arctic fox.

More than proteins for empty stomachs: Wild meat in the BaTonga food system

People and Nature, EarlyView.
Abstract Our paper highlights the limitations of the framework used by many conservation‐focused programmes that incorporate food security objectives. This framework encourages the substitution of wild proteins with domestic proteins by promoting animal farming in communities located near conservation areas.

Patterns of wild meat and other protein consumption in the periphery of Salonga National Park, Democratic Republic of the Congo

People and Nature, EarlyView.
Abstract In Central Africa, human activities are severely impacting terrestrial and aquatic wildlife, threatening the food security of millions of people. Accordingly, sustainable use of wildlife is crucial for the nutrition and livelihoods of many rural communities in the region.

Exploring consumer preferences for wild meat and other animal proteins in Gamba, Gabon: Implications for conservation and management of natural resources alongside extractive industry

People and Nature, EarlyView.
Abstract The town of Gamba in southwest Gabon represents an exceptional example of how the development of an extractive industry (in this case oil production) may impact wild meat consumption in an area of global importance for biodiversity. Studies in the 1990s identified an active wild meat trade; however, no studies have been undertaken since, and ...

Plants, people and their shared heritage: A comparative medicinal and wild food ethnobotany of Albanians, Greeks and Aromanians living in the Gjirokaster area, southern Albania

PLANTS, PEOPLE, PLANET, EarlyView.
Traditional knowledge about wild plants connects people to nature and sustains both cultural identity and biodiversity. This study explores how cultural exchange among Albanians, Greeks and Aromanians in southern Albania shapes the use and naming of medicinal and food plants.

Changements climatiques et biodiversité : comment construire des stratégies « sans regrets » ?

Revue Forestière Française, 2015
Dans un premier temps, nous présentons la problématique de l’effet des changements climatiques sur la biodiversité en soulignant, d’une part, que cette évolution ne peut être prédite sur la seule base de scénarios moyens à l’échelle d’une région et que ...
